…I remember reading in an old trivia book (this would have been around 10th or 11th grade) that, in the majority of men, the left testicle hangs down farther than the right. I believe the book placed the percentage in the mid- to high-90s. My question is this: Why? Being a guy, I understand all too well about the discomfort associated with accidentaly crunching them against each other, but I really can’t see that as evolutionary. Does anyone know how I can locate the answer to this? Ever since I read that statistic, I’ve wanted to know exactly why that happens.
I have no idea. The important question here is: Is your username based on the hamster in the Simpsons? If so, you win the August West Award For Best Use of an Obscure Simpsons Reference In A Username.
…Actually, it is. I couldn’t decide between Superdude and Jubjub. I decided Superdude would be even more obscure, so I went that way. You win the gold star for recognizing it.

One hit of many under “left testicle hang”.

As far as “why?”, I suppose it’s like asking “why do we have five digits instead of four or six?” [shrug] “Just because.”
Ducky, you and your Googleplex. I bow before thee. 
Here’s a WAG for ya all. How about if the decent of the Femoral Artery from the groin area down into the right upper thigh requires the support of additional musculature. And, if said musculature is more pronounced on the starboard side than the port side due to said Artery, perhaps this would cause the right-hand Gem of Live to dangle closer to the body, since the underlying support musculature is more pronounced. Since the left-hand Gem of Life isn’t dangling under possible additional musculature, it has a chance to swing in the wind more, shall we say.
N’est pas?

Yeah, just because we humans are (largely) symmetrical from the outside don’t mean it is so on the inside. The heart i asymmetrically located, as is the liver, digestive organs, circulatory elements, and now we find out the testicles are as well.
Superdude, yours are on the side? Wow. Live and learn.
One almost always hangs lower. The reason is because the friction of walking could be really painful if it was constantly rubbing the twins together.
I’ve often heard that the left testicle is usually bigger and hangs lower. Only, in my case, it’s the complete opposite. Is this unusual, or does testicle hang vary from one guy to another?
Not that I’m worried about it - sometimes we just need to know these things!
Maybe you’re a mirror twin. Has the doctor ever told you your heart’s on the “wrong” side? If not, then maybe you’re different there for the same reason some people are left handed.
Did you know that your right kidney is smaller than your left? (Unless you’re a mirror twin.) And you right testicle is smaller than your left also. Note when you’re cold both your testicles will draw up to your body. They need to be at body heat to work properly, but there they are hanging in the wind, as somebody said. WAG is that the right being smaller would be subject to a greater cooling effect than the left, and hence must be closer to the body. If that be true, and that was just a guess, why is it smaller? Another question.
Supposedly, a woman’s breasts are sized somewhat differently. To confirm this hypothesis, however, an extensive examination of, say, 1600 women would be needed, as would the inevitable manual verification.
Any volunteers?
The left testicle is well known in medicine to be, in most men, lower than the right. Surprisingly, the reason for this is well understood, and has to do with th eblood supply to the testicles, which is not symmetric. The left side drains into the renal vein, the right side into the inferior vena cava IIRC. These veins also divide at different “vertical” levels and this affects the weight of blood in each testicle. It is not uncommon for men to have varicoceles (some 15%), a swelling in the pampiniform plexus which feels like a bag of worms. 97% of these occur on the veins in the left side, your doctor would be more concerned with a right sided swelling – more uncommon equals more likely to be malignant or obstruct the main vein in your abdomen.
